SPECIFICATION forming part of Letters Patent No. 565,821, dated August11, 1896.` Application led May 9, 1896. Serial No. 5901851. (No model.)

To all whom t may concern.-

Be it known that I, WTLLIAM H; WIGGIN, a citizen of the United States,residing at Worcester, county of Worcester, State of Massachusetts, haveinvented certain new and useful Improvements in iVire-Swaging Machines,of which the followingis a full, clear, and exact description, referencebeing had to the accompanying drawings, forming part of thisspecification.

My invention relates to wire-swaging machines employed to compress `wirein the formation of bicycle-spokes, needles, and analogous articles; andthe primary object of my invention is to provide a machine tosimultaneously compress more than a single piece of wire and thereby toenlarge the capacity of a machine of this class; and my invention hasthe further objects of conducing the durability of the operative partsof the machine, accurately controlling during the operation of themachine the degree of action of the swaging-dies upon the wire, andeffecting the relief of the wire from the action of said dies whendesired.

My invention consists, primarily, in the combination, in a wire-swagingmachine, with pairs of swaging-dies, of a support common to and seatedand movable between opposed faces of the anvil members of said pairs ofdies and adapted to sustain said anvil members at different distancesapart from each other,l together with actuating mechanism adapted toimpart swaging movement to the reciprocating members of said pairs ofdies; and my invention comprises the several parts and devices in amachine of this class, hereinafter shown and described, as the same areconstructed and combined to operatein the manner hereinafter set forthand as the same are more particularly specified in the claims herein.

In the drawings, Figure l is a side elevation of a wire-swaging machinecontaining the several features of my invention. Fig. 2 is a front endelevation of the same. Fig. 3 is a side elevation of the stationarysupporting-stand which I preferably employ to hold p Fig. 4 is a `planof the same. Fig. 5 is afront end enlarged sectional elevation of thehead carrying the mechanism for actuating the swaging-dies and thedie-supporting frame, taken on line 5 5 of Figs. 3 and 4. Fig. 6 is anenlarged sectional plan of the same parts, taken on line 6 6 of Fig. 2.Fig.- 7 is a diagrammatic plan of two pairs of swaging-dies in thedie-supporting frame and followers at the outward faces of "the workingmembers of said pairs of dies, together with a preferable form of themovable support seated between the opposed faces of the anvil members ofsaid pairs of dies and mechanism connected to and operated l by saidsupport and preferably employed in connection therewith to effect theadjustment relatively to each other and to sustain in such adjustedposition the anvil members of said pairs of dies in conformity to myinvention; and Fig. 8 is a lateral section of the device preferablyemployed to operatively conneet anvil-blocks to the said movable supportfor the purposes of the invention.

In the drawings, l indicates the main frame or standard of the machine,upon which the voperative parts are mounted.

At 4 is shown a head comprising a recessed shell 4a, in which arecarried the cams 7 for actuating the swaging-dies. For the purposes ofthe principal feature of the invention it is preferable that this headis revoluble, and tol accomplish this it may be mounted on the end of ashaft 2, having bearings on the machine-frame and provided with adriving-pulley-3, as shown.

` The head 4 is preferably constructed with a ring 5 Within theshell 4,and provided with transverse grooves 6, in which are fitted thecam-blocks 7, provided with stems 8, which extend radially through saidring and shell and have their outward ends threaded to severally receivenuts 9, which serve to draw the cam-blocks against the inward face ofsaid ring and hold them in place in the respective transverse groovestherein.

' The die-supporting frame ll is preferably,

forthe purposes of the principal feature of` the invention, stationaryinthe machine; and to accomplish this and to enable it to be seatedwithin the circular range of described camblocks in the revoluble head 4in position to enable the dies supported by it to be actuated by saidcamblocks and to be readily with-` IOO drawn from the head 4 or beunshipped of the machine the said supporting-frame may be convenientlymounted upon and project or overhang from the rearward edge ofabaseplate 12, to which it may be reinforcedly united by ribs I3, thesaid frame and its baseplate and uniting-ribs being desirably cast inone piece, and such homogeneous structure being mounted on a suitablestandard 10, fixed on the machine-frame in front of the head 4, asshown, with the frame 11 projected into the cam-ring in said head.

The die-supportin g frame is preferably seg mental in form, as shown,centrally recessed downwardly from its plane upward face to accommodatethe swaging-dies and their hereinafter-described adj unctive mechanism,and t-he said recess may be closed by a cap 14, held to the plane faceof the segmental frame by screws 15, while the frame is preferablyprovided with laterally-extended way-plates 3l and 32 in its recess,together with a back plate 49 and removable front plates 50 for theconvenient seating therein of the herein* after-described swaging-dies.

In carrying out the primary feature of my invention I employ pairs ofswaging-dies 48 and 4S, seated in the recessed frame 1l and preferablybetween the wayplates 31 and 32 therein, anda support 33, seated andmovable between the opposed faces of the anvil members 48b of said pairsof dies and adapted to sustain said anvil members at different disiancesapart from each other, in conjunction with mechanism, which may be thathereinafter particularly shown and described, in operative engagementwith the reciprocating members 48 of said pairs of dies and the range ofactuating-cams 7, to impart, in connection with said cams, swagingmovement to said working members of said pairs of dies.

In the machine illustrated in the drawings two pairs of swaging-dies areshown seated in the same horizontal plane between the plates 31 and 32in the recess in the frame Il, and it will be found desirable to employthis number of pairs of dies in a machine of this class in conforming tothis principal feature of my invention. The movable support between theanvil members of the pairs of dies is preferably in the form of a wedge,as shown, capable of sliding movementin its seat in the directionparallel and desirably coincident with the axis of the head 4, and whenemployed in connection with two pairs of dies, as shown, the verticalsides of the wedge are the inclines, and its upper and lower faces maybe parallel planes, while the anvil members aforesaid are provided withcorrespondinglyinclined faces opposed to the inclines on the wedge, bymeans of the anvil blocks hereinafter specified. The movement of thesaid wedge-support maybe effected, controlled, and its positionrelatively to the anvil members of the pairs of dies may conveniently bedefined and fixed by means of a lever 37, pivoted in the machine-frameat 38, and one arm of which engages, as by a sector 36 thereon, meshinga rack 35 on the under face of the outer end of the wedge-support, whilethe other arm is in actuating engagement with a rock-'shaft 4l, as by asector 39 on said arm of the lever meshing a pinion 40 on said shaft,the said rock-shaft being provided with an operative handlever 42,adapted to engage adjustable stops 43 and 431l on the machine-frame tolimit and determine the movement thereof, and by means of these devicesthe movement of said wedge-support may be effected and controlled andits position ixedly adjusted during the operation of the swaging-dies.

At 44 and 45 are shown anvil-blocks which are desirably employed in amachine of this class, and are respectively interposed between theopposed faces of the anvil members of the pairs of dies and the supportIn the construction shown these anvil-blocks are respectively seatedbetween the inclined faces of the wedge-support and the opposed faces ofthe anvil members of the pairs of dies, and the faces of the saidanvil-blocks adjacent to the inclined faces of said wedgesupport arecorrespondingly inclined to fit thereto, as shown. The anvil -blocks areharnessed to the wedge-support, so that the movement of the support inone direction by its described actuating mechanism will throw the blocksaway from each other and the movement of the support in the oppositedirection will draw the blocks together, and this may be convenientlyaccomplished by means of plates 4G, attached to the upper and underfaces of said blocks and reaching over the described upper and underfaces of the wedge-support and provided with lips 47, entering grooves34, formed in the said faces of the wedge-support, parallel,respectively, with the inclined side faces of said wedgesupport. It isevident that in this arrangement the oscillation of the rock-shaft 4I,and consequent vibration of the lever 37, and reciprocal movement of thewedge support will, by affecting the movement of the anvilblocks, asdescribed, cause the anvil members of the pairs of dies to more or lessapproach or recede from the working members thereof, so that in this waythe degree of action of the swaging-dies upon the wire they arecompressing may be accurately controlled during the operation of themachine, or the entire relief of the wire from the action of said diesmay be effected at pleasure.

The mechanism which I preferably employ in connection with the range ofcam-blocks to actuate the dies comprises levers 17 and 18, working inlateral recesses 16 in the die-sup porting frame, and respectivelypivoted at -their upper and lower ends on studs 19 and 20, and providedat their free ends with friction-rolls 2l, and governed byspring-actuated bolts 22 to vibrate the levers to carry theirfriction-rolls into the path of the cams 7, together withfollower-blocks 29 and 30, respec- IOC IIO

tively, carried by said levers 17 and 18, and adapted to play in thecentral recess in the die-supporting frame and impinge upon the outwardfaces of the reciprocating members of the respective pairs of diestherein.

The actuating devices for the bolts 22 may conveniently be composed ofthe spiral springs 23, seated about said bolts in recesses in themachine-frame, and tension-adjusting bolts 24, acting upon the springsand controlled by nuts 25, which are adapted to be turned on their boltsby a Spanner, but are held from endwise movement within slots 26, asshown.

The follower-blocks 29 and 30 may be conveniently seated between theplates 31 and 32 in the die-supporting frame and may be respectivelyconnected to the levers 17 and 18 by links 28, seated at one end insemicircular recesses 27. in the levers and at their opposite ends insimilar recesses in said blocks.

The hereinbefore-described front plates 50 on the recessed-die-supporting frame are preferably provided with outwardly-flared lateral apertures52, which severally inwardly register with the entrances to the matricesin the respective sectional swaging-dies, as shown, to readily guide thewire fed to the dies into said matrices, and the back plate 49 andrearward part of the frame 11 are provided with apertures 53, whichregister with the exits from the said matrices in said dies and fallwithin the internal diameter of the shaft 2, which is hollow for thepurposes hereof, so that the wire may extend backward from thedicsthrough said back plate and frame and into the hollow shaft.

The front plates 50 are desirably held in place between the plates 31and 32 by segmental-headed screws 51, seated near the ad-- jacent edgesof the front faces of the plates 31 and 32, respectively, so that byturning said screws to bring the plane portions of their segmental headscoincident with the said edges of said plates 31 and 32 the plates 50and the dies may be readily unseated and Withdrawn from the die-frame.

It will be understood that the die-trame herein shown and described,together with the head for holding the cams and the mechanism foroperatively connecting the actuatingcams to the die-followers, as hereinset forth, may be employed in connection with andto impart swagingmovement to a single pair of dies; and it will be further understoodthat mechanism, such as is well known and employed for the purpose, maybe used for holdl ing and feeding the wire to be swaged to the 4provided on anvil-blocks interposed between said support and the anvilmembers of said pairs of dies, together with actuating mechanism adaptedto impart swaging movement to the working members of said pairs of dies;substantially as and for the purpose specified.
